Symmetry Breaking Bulk Effects in Local D-brane Models
We study symmetry breaking effects in local D-brane models that arise as a
result of compactification, taking models constructed on C^3/Z_3 as prototype.
Zero-modes of the Lichnerowicz operator in cone-like geometries have a power
law behaviour; thus the leading symmetry breaking effects are captured by the
modes with the lowest scaling dimension which transform non-trivially under the
isometry group. Combining this with the fact that global symmetries in local
models are gauged upon compactification we determine the strength and form of
the leading operators responsible for the symmetry breaking. We find a
hierarchical separation in the size of symmetry breaking parameters.Comment: 13 pages, 1 figure; v2 typos removed; v3 JHEP versio

Proposal to Encode the Pau Cin Hau Alphabet in ISO/IEC 10646
This is a proposal to encode the Pau Cin Hau script in the international character encoding standard Unicode. This script was published in Unicode Standard version 7.0 in June 2014. Pau Cin Hau is a liturgical script for the Laipian religion. It was originally designed to write the Tedim language, a Chin language in western Myanmar, but the script also includes characters for representing sounds of other Chin languages

Proposal to Encode the Mahajani Script in ISO/IEC 10646
This is a proposal to encode the Mahajani script in the international character encoding standard Unicode. This script was published in Unicode Standard version 7.0 in June 2014. Mahajani is a script that was used across northern India until the mid-20th c. It was used to write Hindi, Marwari, and Punjabi. The script is no longer in general use
Final Proposal to Encode the Khudawadi Script in ISO/IEC 10646
This is a proposal to encode the Khudawadi script in the international character encoding standard Unicode. This script was published in Unicode Standard version 7.0 in June 2014. Khudawadi is an historic script, used to write the Sindhi language, which is spoken in Pakistan and India. In the 1860s it was selected to be the standard for education and administration. In late 19c, Arabic became the official writing system for Sindhi. In India, Sindhi is also written in the Devanagari script
